BL manhua isekai,/transmigration recommendations

I'm looking for bl manhua ( Chinese comic ) where the main character is transmigrated to his favorite comic or novel and has knowledge of future events even if the plot changes because of his actions. He could be placed into a side character or the villain but I want him to have a imrelationship with either the novel's protagonist or antagonist. I want him to make friends with other characters too so it won't just be the two male leads. No abuse or toxic love or anything like that. Romance with drama, action, it adventure is great but no abuse. Any recs?
